Question

In refraction, the incident ray, refracted ray and the normal lie on the same ______________

Answer 1

Laws of Refraction:

1. The incident ray refracted ray and the normal all lie in the same plane.
2. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for a given pair of media. This constant is called the refractive index.

Hence, In refraction, the incident ray refracted ray, and the normal lie on the same plane.
